Microcellular propagation at UHF and microwave frequencies for personal communications

In this paper we present theoretical models for microcellular communications at UHF and microwave frequencies. For rural microcells, a vectorial analysis of the two-ray model is carried out, and comparisons between the developed model and measurements reported in rural areas of New Jersey and San Francisco Bay are provided. For urban microcells, the street is three-dimensionally modeled as a deterministic multislit waveguide channel, according to its database, and vectorial analysis is also taken into account. For the 3D street model, comparisons in good agreement with measurements reported in New York City are performed. Comparisons provided with measured data show that the models proposed can be very useful tools toward increasing theoretical analysis in spite of empirical analysis in the field of prediction.
